"agent control utility: unable to access parameter file"
*Cause: The agent control utility was unable to access its parameter
file. This could be because it could not find its admin
directory or because permissions on directory were not correctly
*Action: The agent control utility puts its parameter file in either
the directory pointed to by the environment variable AGTCTL_ADMIN
or in the directory pointed to by the environment variable
TNS_ADMIN. Make sure that at least one of these environment
variables is set and that it points to a directory that the
agent has access to.
